the battery pack to remain in the charger for 15 to 30
minutes. When the battery pack reaches normalvoltage

CHARGING A HOT BATTERY PACK
When using the tool continuously, the batteries in the
battery pack will become hot. You should let a hot battery
pack cool down for approximately 30 minutes before
attempting to recharge. When the battery pack becomes
discharged and is hot, this will cause the green LED to
come on instead of the red LED. After 30 minutes, reinsert
the battery pack in the charger. If the green LED continues
to remain on, return battery pack to your nearest Ryobi
Authorised Service Centre for checking or replacing.
OPERATION
NOTE:
This situation only occurs when continuous use of
the tool causes the batteries to become hot. It does not
occur under normal circumstances. Refer to
“CHARGING
A COOL BATTERY PACK”
for normal recharging of
batteries. If the charger does not charge your battery pack
under normal circumstances, return both the battery pack
and charger to your nearest Ryobi Authorised Service
Centre for electrical check.
